You've been honest about where you are. That's the hard part done, and plenty of people never manage it. Starting from here has one big advantage: people who are new to training tend to improve fastest at the start, so you'll notice it.1 This path keeps things simple. Small steps, wins you can count, and nothing that needs you to be fit already.
Your first step
Spend five minutes on the effort scale, so you know what "moderate" really feels like. Most people starting out either go far too hard or not quite hard enough.
Learn the effort scaleYour first few weeks
- Start where you areSomething is better than nothing. A brisk walk counts. So does a short session on a gym bike. The aim of the first week is to do it, not to be good at it.
- Aim for moderateBreathing faster, feeling warmer, able to talk but not sing. That's the NHS description of moderate effort.2 It's enough to make progress without dreading the next session.
- Add a little each weekA few more minutes, or one more session. The NHS guideline for adults is 150 minutes of moderate activity a week plus strength activities on 2 days.2 Treat it as somewhere to build towards, not a test you fail on day one.
- Count your winsWrite down every session, however small. The first time you go two weeks without missing one is worth noticing.
